Includes and browser detection

Anon

Hello,

I'm quite new to PHP so pls bear with me 🙂

I was taking a look at this website today as I have been looking around for good methods of browser detection/redirection

http://www.awebcompany.net/ie.php?incdoc=docs/web.design

I have written the js needed to detect what browser is what, and can redirect the user to whichever page, but I would like to know how they are being able to ?incdoc= in the URL and only have the center of the page change. Obviously meaning that the only thing that changes as in SSI is where the call is.

If anyone could help me I'd be very greatful,

Thanks

I cannot tell you the way they did it, but i can tell you the way i would do it....

use this javascript:
<script>
function WM_toggle(id){
if (document.all){
if(document.all[id].style.display == 'none'){
document.all[id].style.display = '';
} else {
document.all[id].style.display = 'none';
}
return false;
} else if (document.getElementById){
if(document.getElementById(id).style.display == 'none'){
document.getElementById(id).style.display = 'block';
} else {
document.getElementById(id).style.display = 'none';
}
return false;
}
}
</script>
Then do something like this in the middle of your page

<div id="thisid" style="display: block">
all the stuff
</div>
<div id="thisotherid" style="display: none">
all the other stuff
</div>

now have a link somewhere that looks like this:
<a href="#" onClick="WM_toggle("thisid"); WM_toggle("thisotherid"); return false;">Open #1, close #2</a>

If you understand that, this is what it does:
It uses cascading style sheets,
if you have
<div id="this" style="display: block">
<? include('whatever.htm") ?>
</div>
it will display that page you included, if the style is changed to display: none
it wont display
Using the javascript you can toggle the display between clock and none, as to switch between pages
This could put a lot of text on your page in the long run, but that is a way it could work
Peace

i would do the check on the server side, with the $HTTP_USER_AGENT variable... and dependend on which browser is used, do the redirection...

For browser detection Iuse:
<?
if((ereg("Nav", getenv("HTTP_USER_AGENT"))) || (ereg("Gold", getenv("HTTP_USER_AGENT"))) || (ereg("X11", getenv("HTTP_USER_AGENT"))) || (ereg("Mozilla", getenv("HTTP_USER_AGENT"))) || (ereg("Netscape", getenv("HTTP_USER_AGENT"))) AND (!ereg("MSIE", getenv("HTTP_USER_AGENT")))) $browser = "ns";
elseif(ereg("MSIE", getenv("HTTP_USER_AGENT"))) $browser = "ie";
else $browser = "Other";
?>

for browser detection. it will only return whether it's netscape, ie or other but it's a start. There will be more specific ones out there if you look.

You might want to do a OS check as well so you can tailor your pages for eveyone, I use:
<?
unset ($platform);
function browser_get_platform() {
global $platform;
return $platform;
}
if (strstr($HTTP_USER_AGENT,'Win')) {
$platform = 'Win';
} else if (strstr($HTTP_USER_AGENT,'Mac')) {
$platform = 'Mac';
} else if (strstr($HTTP_USER_AGENT,'Linux')) {
$platform = 'Linux';
} else if (strstr($HTTP_USER_AGENT,'Unix')) {
$platform = 'Unix';
} else {
$platform = 'Other';
}
?>
which seems to work a treat.

You can then either redirect to specific pages or include specific pages. Or build a series of if and else if statements into a single page that will control the output for the specific user. This way you won't end up with masses of files.
